My ds seems to have the problem of relaxing enough to go. It is almost a nightly ritual to put him to bed and within a half-hour have him needing a change.

I like the idea of giving him a toy he can only have on the toilet, but the timing of his bm is bad. We already struggle getting him to go to bed...the last thing I want to do is encourage him to sit on the toilet from 8pm - 9...waiting for him to poo. What can be done about changing his body's routine?
